PURPOSE:To eliminate unpleasant feeling by the oppressive force of the seat belt, by providing the tensionless mechanism wherein the click is provided to the operating lever, and the slack of the belt is once rolled in, and then, a small length of the belt is pulled out. CONSTITUTION:When the motorist moves his body forward from the tensionless posture, the slip cam 10 rotates with the ratchet 9 and the outer circumference of the cam pushes the tip of the click 17 outwards. Then, the click 17 goes off the ratchet 9 and the belt is pulled out. When the motorist returns to his former posture, the click 17 again engages with the ratchet 9 as the slip cam 10 rotates to the former position where the recess 10a of the slip cam 10 meets with the click 17. The seat belt becomes the tensionless condition again at the first position. |
